摘　　要：数字扫描变换器(DSC)是医用B超的重要部件,有坐标变换和插值两个关键点。根据实际项目的需求,在分析DSC原理的基础上,确立了以双线性插值和CORDIC算法完成坐标变换的设计思想,并给出其在FPGA中的实现和硬件仿真。结果表明,其运行速度快,结构简单,满足应用需求。The digital scan converter （DSC） is an important part of the medical Bultrasonic, coordinate transformation and in terpolation are two key points in its design. According to the actual needs of the project, based on analysis of the DSC principle, this paper establishes a coordinate transformation design thinking which is completed by the bilinear interpolation and the CODIC algorithm, and gives its implementation and hardware simulation in the FPGA. The results show that its running speed and simple structure meets the application requirements well.
